Application April 5, 1935, Serial No. 14,944 In Great Britain April 11, 1934 6 Claims.

This invention relates to mineral water siphon bottles and similar containers for storing and dispensing aerated liquids'under pressure, and has for its object to provide a new and improved means for effecting the discharge of the contents of containers of the kind referred to so that the aerated liquid can be dispensed with a minimum loss of aeration.

According to the present invention a siphon bottle er similar container of the kind referred to is provided with means to permit the escape `of excess gas collected above the level of the aerated liquid in advance of the delivery of such liquid through the discharge head when the valve therein is operated, so as to reduce the internal gas pressure sufficiently to effect a quiet and relatively unbroken delivery of the aerated liquid.

In a convenient manner of carrying out the invention, a non-return gas release valve is arranged in the carrier by which the Siphon tube is suspended` in the container, or inthe upper part of the Siphon tube when the carrier is dispensed with, so as to normally close one or more apertures formed in such carrier or tube in order to interconnect the gas space above the level of the liquid stored in the container, with the valve in the discharge head.

The non-return release valve is automatically opened by unbalanced pressure of the gas trapped in the container asthe valve in the discharge head is operated, so that excess gas escapes past the release valve through the valve in the discharge head in advance'of the aerated liquid. rising through the siphon tube.

To facilitate the escape or shift of gas in ad- Vance of the delivery of aerated liquid through the discharge head a non-return liquid release valve is arranged in the siphon tube or its carrier, as the case may be, below the gas vent aperture or apertures therein so as to close the upper end of the siphon tube and prevent the aerated liquid rising therethrough until the liquid release valve is opened by the progressive operation of the valve in the discharge head.

The invention is further described with reference to the accompanying drawing, wherein similar references indicate corresponding parts.

Fig. 1 is a fragmental vertical sectional view of a mineral water Siphon bottle illustrating one embodiment of the invention adapted for use with a discharge or siphon head of short lever pattern. Fig. 2 is a detail view further illustrating a spring for controlling the non-return gas relief valve shown in Fig. 1. Figs. 3 and 4 are respectively vertical sectional views illustrating other embodiments of the invention for use with mineral water or like bottles or containers furnished with discharge heads of the short lever pattern, and Fig. 5 a cross section View on the line V-V Fig. 4.

As shown in the drawing, the siphon tube I is suspended in the bottle 2 by means of a carrier 3 in which one or more apertures 4 is or are formed, whichk apertureor apertures is or are normally closed by a non-return `gas released valve 5 10 mounted iny the carrier for this' purpose, so that when the carrier 3- and its siphon` tube together with the discharge head 6 are assembled to the bottle as indicated in Fig. 1, the space a above the level of the aerated liquid b stored in the 15 bottle can be directly connected via the aperture or apertures 4 and gas release valve 5 in the carrier, with the valve l of the discharge head.

In the construction shown in Fig. 1, the carrier 3 comprises a detachable extension 3a that is cast 20 or otherwise secured on the siphon tube I, and forms an internally threaded socket adapted for engagement with the externally threaded lower end of' the carrier, an annular packing 8 being arranged in the socket-like detachable extension 25 3a so as to form a gas tightjoint betweenpthe carrier and its extension when these elements are assembled,v as indicated.

The upper part of the carrier 3 is adapted to `form a socket 9 the exterior of which is ilanged 30 at 9a, and dimensioned to fit intoV the body of the discharge head 6 and form therein an annular groove for the usual gasket or neck washer I 0 that forms a gasv tightjoint between the lip 2a of the bottle and the discharge head 6, and also 35 the support for the carrier 3.

A plurality of inclined apertures or passages 4 are formed in the annular wall of the carrier 3, the lower ends of which passages terminate in external openings 4a, while their upper ends 40 terminate in an annular connecting groove 9b formed in the bottom ofthe socket 9 in which Ysocket is arranged the non-return gas release valve 5. Such gas releaser valve consists of an annular washer of India-rubber or other suitable elastic material that is adapted to lie flat on the bottom of the socket 9 so as to normally seal the connecting groove 9b therein. The valve 5 so formed isk controlled by a flat annular plate spring 5a furnished with internal radial fingers 5b (see Fig. 2) that is superposed upon the elastic valve 5, which latter, together with its controlling spring is adjustably secured in the socket 9 by an externally threaded ring Il 55 adapted to engage the counterpart internally threaded wall 9c of the socket.

The ring II is slotted as indicated at IIb for engagement with a box spanner or other instrument for screwing and unscrewing the same.

The bore of the carrier 3 is formed at its upper end with an internally coned seating I2a for a glass or other suitable ball valve r'/I2, which is normally held against vits seating I2a by a spring I3 carried on the upper endof the siphon tube I so as to close the bore of the carrier and its siphon tube I.

The discharge head 6 is furnished as usual with a spout I4 and an internal waterway I5 which is surrounded by a downwardly extending annular iiange I5a that forms the seating for the valve 1 of the discharge head, such valve being carried as usual by a spring controlled spindle 1a through which it is connected with the operating lever I6 of the discharge head; the lower end or skirt of the discharge head 6 is internally threaded as indicated at 6a for engagement with thecounterpart external thread I1a of the neck ring I1 by which the discharge head is secured upon the neck of the bottle 2 in known manner so as to compress the gasket or neck washer IU against the lip of the bottle and form a gas tight joint.

The valve 1 in the discharge head opens downward from its seating by manipulation of the operating lever I6 in the ordinary manner. As the valve 1 opens the gas pressure in the interior of the discharge head 6 drops, and if the resistance of the gas release valve 5 and its controlling spring is less than the gas pressure in'the space a above the liquid level in the bottle 2, the release valve 5 is momentarily opened bythe unbalanced gas pressure, so that excess gas escapes from the space a in the bottle past the gas release valve 5 and the valve 1and as the opening of the latter valve continues its extension 1b bears against and opens the liquid release Valve I2 against the resistance of its spring I3 and the internal pressure in the Siphon tube, so that the aerated liquid rises through the tube I past the open release valve I2 and follows the previously vented gas past the valve 1 to the spout I4 from which it is quietly delivered in av state of maximum aeration.

On releasing the Valve operating lever I6 of the discharge head the valve 1 in the latter closes, so releasing the valve I2 in the carrier,

which is simultaneously closed by its controlling spring, while the gas pressure below the closed valve 1 of the dischargel head is restored by the passage of gas through the gas release valve 5 from the interior space a of the bottle or like container.

In the construction shown at Fig. 3 a plurality of apertures 4 is formed in the wall of the tubular carrier 3, the inner ends of such apertures terminating in a connecting groove 4:1: formed in the inner surface of the carrier, in the bore of which the gas release valve 5 is mounted.

The gas release Valve 5 is formed by a sleeve of India-rubber cr other suitable material, the lower end 5m is thickened and externally serrated and cemented or otherwise secured gas tight in counterpart serrations in the bore of the carrier, below the groove 4a: therein, as indicated at 5y, while the elastic valve 5 formed by the upper-part of the sleeve is free, and normally seats gas tight against the concentric surface 5a above the groove 4x in the bore of the carrier.

The thickened lower end 5a: of the sleeve is internally coned to form the seating I2a for the spring controlled ball valve I2, that normally closes the bore of the carrier 3, and siphon tube, under the influence of its controlling spring I3 that is mounted in the detachable extension 3a 5 which it is suspended from the gasket or neckwasher III, thatl is clamped between the lip 2a of the bottle and the discharge head 6, when this lattertogether with the carrier 3 are assembled l5 to the bottle 2 as previously described.

, The valve 1 of the discharge head is furnished with an extension 1b and is enclosed by the ared upper end of the carrier 3 and normally seats on the annular elastic seating piece I5a to 20 seal the waterway I5 through the discharge head, while the ange 3m of the carrier is clamped gas tight between the seating piece I5a and the gasket or'neck washer I0.

In the modification shown, in Figs. 4 and 5 a 25 single inwardly flared aperture 4 is formed in the wall of the tubular carrier 3, and is normally closed by the gas release valve 5, consisting of a ball, under the inuence of a horizontally disposed spring 2II loosely mounted in the groove 4x 30 in the bore of the carrier, in which groove termi-- nates the flared inner end of the aperture 4.

In this construction the carrier 3 is formed in one piece, its lower end being secured about the top of the siphon tube I, and is outwardly flared 35 towards its upper end, which terminates in an external flange 3m, by which the carrier is suspended in the bottle or container, as described with reference to Fig. 2. The valve 1 oi the 4discharge head is enclosed by the upper end 0I 40 the carrier, so that when such valve is opened it bears against and operates the valve I2 mounted in the carrier and controlled by the spring I3 arranged in the lower end thereof.

As the valve I opens, the pressure of excess 45 gas trapped in the space a above the liquid in the bottle automatically opens the gas release 5, through which excess gas ls vented, and escapes past the valve 1, the progressive movement of which then opens the valve I 2, so allowing the 50 aerated liquid to rise through the tube I and flow to the outlet of the discharge head, as previously described.

In this construction, the valve I2 is furnished with a tubular stem 2I provided with lateral 55 openings 22, which stem works ln a guide 23 ln which the seating I2a. is arranged for the valve I2. The guide 23 is secured in a parallel section 3k of the bore of the carrier 3 below the groove l 4x therein, while the valve I2 is normally closed 00 by its spring I3.

The upper end of the tubular stem 2I projects beyond the guide adjacent to the lower end of the valve 1 of the discharge head.

As the valve 1 is opened pressure of excess gas 65 trapped in the space a within the bottle automatically opens the gas release valve 5, so venting excess gas in advance of the aerated liquid vwhich rises through the tube I and the openings 22 in the tubular stem 2l of the valve I2 as the latter is opened by the progressive operation of the valve 1 in the discharge head.

As the valve 1 closes the valve I2 simultaneously closes under the inuence of its controlling spring I3, so preventing further liquid rising in the Siphon tube until the next operation.
